2 linked sky+ boxes - help!

I currently have Sky+ downstairs with an aerial link to my TV upstairs with a TV Remote Eye upstairs. This allows me to watch Sky+ upstairs and change programs, set up new recordings from upstairs via the remote eye.

I am having Sky+160 installed this weekend: replacing my standard Sky+ downstairs and the old Sky+ moved upstairs. I want to be able to:

a) Link both Sky+ boxes to the TVs in the other rooms;
b) Add another Remote eye so I can record programs on either Sky+ box & watch in either rooms.

How should I do this? Can I use 2 remote eyes this way? If so, how do I prevent the signal from the remote handset hitting both Sky+ boxes? If I click to record wont both sky+ boxes receive the command, one directly & one via the remote eye?

Help please!

can be done but needs a more complex solution which will cost far more money.......as you have
